Patent DE-2951486-A1 (DE)
Inventor: DEVRIENT LUDWIG
IPC: D21H21/46
Filed: 1979-12-20
Abstract: A check paper is being described which is protected against falsifications and forgeries. Crushable micro capsules are being embedded in check paper which contain on one hand a leuco ink and on the other hand a color acceptor. The color acceptor can also be stored in the body of the paper without the use of micro capsules. The leuco ink and the color acceptor react together under color development or color changes if the micro capsules burst through imprinting or other local pressure application to the paper surface. Thus, a character written on the paper surface becomes visible within the body of the paper and cannot be forged anymore.

Title: Centrifugal casting of pneumatic tyres - using core with inflatable zenith portion for locating reinforcement plies
Inventor: BODEN HEINRICH
IPC: B29D30/08
Filed: 1980-01-19
Abstract: Reinforced pneumatic tyres are made from a polyurethane elastomer by a centrifugal casting process. The core has tread parts which can be deformed outward by compressed air or hydraulic fluid so that they fix the reinforcement plies by friction in the desired final position. When this outer layer has been injected and has fixed the plies, the core tread parts are deflated and the rest of the elastomer is filled into the remaining space. This is a reliable way of embedding reinforcement plies in polyurethane elastomer tyres without risk of internal flaking.

Patent DE-3021799-A1 (DE)
Inventor: HETTICH HEINZ
IPC: B21G1/08
Filed: 1980-06-11
Abstract: A method of manufacturing hollow needles from round metal blanks in order to form a needle which has an inner front portion with a front end tapering to a point and a rear portion having a larger diameter than the front portion and forming a mounting shank, comprising forming a longitudinally extending needle guide to the needle such that the guide is open at the rear end of the mounting shank and tapers from a substantially uniform depth along a major portion of its length to a minimum depth adjacent the tip. The channel is of a shape to receive substantially cylindrical cross pins having an appended piece of filament which form a part of fasteners for tags, buttons and similar items to be attached to carrier materials such as textiles. The method is carried out by the use of a disc-shaped miller cutter which has U-shaped convex teeth for milling the central area of the channel in side tooth portions for milling shoulders on each side of the channel which are of lesser depth than the channel. The side tooth portions are employed to mill inclined V-recessed surfaces on each side of the central channel. In accordance with the inventive method after the channel is milled it goes to extend from the rear end along the inner front portion and taper to substantially a minimum depth at a spaced location from the tip, a stamping tool is used to engage into the inclined surfaces formed by the side teeth so that these surfaces are pressed inwardly to close a major portion of the length of the channel but without closing a release portion adjacent the tip of the needle which is less substantially equal to the width of the channel.

Title: Plastics moulding with fibre mat reinforcement - made from fibres mats initially joined and pressed then impregnated with liq. resin in evacuated mould
Inventor: RUDOLF ARTUR
IPC: B29C43/12
Filed: 1980-10-31
Abstract: Plastics mouldings with fibre mat reinforcement are produced by first superimposing sheets or blanks of fibre mat in a mould, bonding them together at isolated points after each second or third layer by use of an agent which softens the mat, compressing them to a fraction of their former thickness then maintaining them under this pressure while saturating them with liquid resin and leaving them to set under pressure. Pref. the temporary or initial bonding points are produced by sprinkling on an evaporating solvent or by heat. Pref. during the final impregnation process, the internal cavity of the mould is evacuated to permit ingress of the resin. Evaporation of the temporary solvent may be promoted by a hot air flow. Improved strength and homogeneity are achieved.
